Heat Exchangers — Air Cooler, Hydraulic Powered

With this new generation of Universal Hydraulik LKI oil-coolers, noise level has been reduced. These coolers are ideally suited for mobile installations – for the cooling of hydraulic or lubricating oils. The housings have been optimized, in order to produce the very low noise level and to make the cooler range as comprehensive as possible. The smaller models are also available as single or dual versions, thus covering oil-cooling requirements for both low and high oil through-flow volumes.
